For PUNIT device, ISPDRIVER_IPC and GTDDRIVER_IPC resources are not
mandatory. So when PMC IPC driver creates a PUNIT device, if these
resources are not available then it creates dummy resource entries for
these missing resources. But during PUNIT device probe, doing ioremap on
these dummy resources generates following warning messages.
intel_punit_ipc: can't request region for resource [mem 0x00000000]
intel_punit_ipc: can't request region for resource [mem 0x00000000]

It's important for the driver to provide a R/W ioctl to ensure that
two competing userspace processes don't race to provide or read each
others data.
This userspace character device will be used to perform SMBIOS calls
from any applications.
It provides an ioctl that will allow passing the WMI calling
interface buffer between userspace and kernel space.
This character device is intended to deprecate the dcdbas kernel module
and the interface that it provides to userspace.
To perform an SMBIOS IOCTL call using the character device userspace will
perform a read() on the the character device. The WMI bus will provide
a u64 variable containing the necessary size of the IOCTL buffer.
The API for interacting with this interface is defined in documentation
as well as the WMI uapi header provides the format of the structures.
Not all userspace requests will be accepted. The dell-smbios filtering
functionality will be used to prevent access to certain tokens and calls.
All whitelisted commands and tokens are now shared out to userspace so
applications don't need to define them in their own headers.

For WMI operations that are only Set or Query readable and writable sysfs
attributes created by WMI vendor drivers or the bus driver makes sense.
For other WMI operations that are run on Method, there needs to be a
way to guarantee to userspace that the results from the method call
belong to the data request to the method call. Sysfs attributes don't
work well in this scenario because two userspace processes may be
competing at reading/writing an attribute and step on each other's
data.
When a WMI vendor driver declares a callback method in the wmi_driver
the WMI bus driver will create a character device that maps to that
function. This callback method will be responsible for filtering
invalid requests and performing the actual call.
That character device will correspond to this path:
/dev/wmi/$driver
Performing read() on this character device will provide the size
of the buffer that the character device needs to perform calls.
This buffer size can be set by vendor drivers through a new symbol
or when MOF parsing is available by the MOF.
Performing ioctl() on this character device will be interpretd
by the WMI bus driver. It will perform sanity tests for size of
data, test them for a valid instance, copy the data from userspace
and pass iton to the vendor driver to further process and run.
This creates an implicit policy that each driver will only be allowed
a single character device. If a module matches multiple GUID's,
the wmi_devices will need to be all handled by the same wmi_driver.
The WMI vendor drivers will be responsible for managing inappropriate
access to this character device and proper locking on data used by
it.
When a WMI vendor driver is unloaded the WMI bus driver will clean
up the character device and any memory allocated for the call.

When a userspace interface is introduced to dell-smbios filtering
support will be used to make sure that userspace doesn't make calls
deemed unsafe or that can cause the kernel drivers to get out of
sync.
A blacklist is provided for the following:
- Items that are in use by other kernel drivers
- Items that are deemed unsafe (diagnostics, write-once, etc)
- Any items in the blacklist will be rejected.
Following that a whitelist is provided as follows:
- Each item has an associated capability. If a userspace interface
accesses this item, that capability will be tested to filter
the request.
- If the process provides CAP_SYS_RAWIO the whitelist will be
overridden.
When an item is not in the blacklist, or whitelist and the process
is run with insufficient capabilities the call will be rejected.

The dell-smbios stack only currently uses an SMI interface which grants
direct access to physical memory to the firmware SMM methods via a pointer.
This dispatcher driver adds a WMI-ACPI interface that is detected by WMI
probe and preferred over the SMI interface in dell-smbios.
Changing this to operate over WMI-ACPI will use an ACPI OperationRegion
for a buffer of data storage when SMM calls are performed.
This is a safer approach to use in kernel drivers as the SMM will
only have access to that OperationRegion.

This splits up the dell-smbios driver into two drivers:
* dell-smbios
* dell-smbios-smm
dell-smbios can operate with multiple different dispatcher drivers to
perform SMBIOS operations.
Also modify the interface that dell-laptop and dell-wmi use align to this
model more closely. Rather than a single global buffer being allocated
for all drivers, each driver will allocate and be responsible for it's own
buffer. The pointer will be passed to the calling function and each
dispatcher driver will then internally copy it to the proper location to
perform it's call.
Add defines for calls used by these methods in the dell-smbios.h header

Currently userspace tools can access system tokens via the dcdbas
kernel module and a SMI call that will cause the platform to execute
SMM code.
With a goal in mind of deprecating the dcdbas kernel module a different
method for accessing these tokens from userspace needs to be created.
This is intentionally marked to only be readable as a process with
CAP_SYS_ADMIN as it can contain sensitive information about the
platform's configuration.
While adding this interface I found that some tokens are duplicated.
These need to be ignored from sysfs to avoid duplicate files.

If the buffer size or header don't match, this is a good indication

The fusb302 driver as merged in staging uses "typec_fusb302" as i2c-id
rather then just "fusb302" and needs us to set a number of device-

One of the properties set is max-snk-mv which makes the fusb302 driver
negotiate up to 12V charging voltage, which is a bad idea on boards
which are not setup to handle this, so this commit also adds 2 extra

The GP-electronic T701 has its LCD panel mounted upside-down, initially
my plan was to fix this by transparently rotating the image in the i915
driver (my "drm/i915: Deal with upside-down mounted LCD" patch), but
that approach has been rejected instead the kernel will now export
a "panel orientation" property on the drm-connector for the panel and
let userspace deal with it.
But userspace expects the touchscreen coordinates to match the panel
coordinates *before* applying any rotation, so now that we no longer hide
the upside-down-ness of the LCD panel from userspace the coordinates being
generated are wrong and we need to apply a rotation of 180 degrees to the
coordinates to fix this.

which states "If the left side is elevated, X increases (becomes positive)".
When tested, on lifting the left edge, x values became increasingly negative
thus indicating an inverted x-axis on the installed lis3lv02d chip.
This was compensated by adding an entry for this device in hp_accel.c

"/proc/sys/kernel/sched_itmt_enabled" on i9-7900x with Asrock x299
Taichi system even if he enabled "Turbo 3.0" in the BIOS.
The problem is that even if one core max is 200MHz more than others, the
current implementation couldn't enumerate that with the way the system
is configured.
The system by default configured for legacy mode (no HWP or speed shift
technology), in this mode only way we can enumerate via the mail box
interface as implemented in this driver. We were planing to only use
this driver for Broadwell, but we need to extend this because some
Skylake system has same issue as Braodwell systems.
On this system BIOS allows to change to HWP mode, where we expect that
we can enumerate favored core with ACPI-CPPC. But on this system the
core priority is 0xff for all cores in CPPC object. So this is not an
option.
Hence this change allows Skylake systems to be enumerate favored core
similar to Broadwell in legacy mode.

For devices not instantiated through ACPI the i2c-client's device-name
gets set to <busnr>-<addr> by default, e.g. "0-0022" this means that
the device-name is dependent on the order in which the i2c-busses are
enumerated.
In some cases having a predictable constant device-name is desirable,
for example on non device-tree platforms the link between a regulator
and its consumers is specified by the platform code by setting
regulator_init_data.consumers. This array identifies the regulator's
consumers by dev_name and supply(-name). Which requires a constant
dev_name.
This commit adds a dev_name field to i2c_board_info allowing
platform code to set a contstant dev_name so that the device can
be identified by its dev_name in other platform code.
